Kato Tangless(R) Inserts from Tower Reduce Installation Time and Cost


The patented design of the Kato Tangless(R) CoilThread(R) insert available from Tower Fasteners greatly reduces the installation time and costs associated with the use of threaded inserts since tang removal is not required.

The resilient, high-tension coil inserts are installed with Kato hand, air-driven or electric tools featuring a special head that grips and drives the insert. The bi-directional design of the Tangless insert eliminates the need to orient each part, as with other inserts, and saves additional time in manufacturing applications that require accounting and inspection of each removed tang. The Kato Tangless inserts do not require special tang break-off and tang removal tools.

The high-tension coils of a Tangless CoilThread insert undergo a diameter reduction when installed, and the outward spring-like tension of the coil locks the insert into place. Each coil can flex independently for the greatest amount of thread surface contact, improving static and dynamic load bearing capabilities.
